Trait IncludeCollection 

pub trait IncludeCollection<T>: Entity {
    // Required method
    fn set_included_collection(
        &mut self,
        navigation: &str,
        values: Vec<T>,
    ) -> Result<(), OrmError>;
}

Contract generated for entities that can receive an included collection navigation value.

This is used by DbSetQuery::include_many::<T>(...) for has_many navigations. The query layer groups duplicate root rows before assigning the loaded collection.

Required Methods

fn set_included_collection( &mut self, navigation: &str, values: Vec<T>, ) -> Result<(), OrmError>

Attaches loaded collection values to the field named by navigation.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
